I don't hate to be the blunt voice here:
If you want match performance, you need to shoot match ammo, and do it through a decent rifle.
A decent rifle can look pretty good with good ammo, but NO rifle shoots crappy ammo well. They may be fine at 25 feet, 50 feet, maybe even 50 yards if you're not shooting too small a target, but lower grade ammunition will shoot 2-3 MOA at 100, and worse further.
I have one rifle that will keep CCI 0035 in a 6-8" circle at 200 yards, which is really saying something, since even some of the mid-grade target ammo will go 2-3" wide by 8" tall. But the same rifle will do 2" or under WITHOUT a tuner using Eley from black or red boxes.
Hey, if I could keep ONE case of ammunition on hand all the time for the rest of my life, it would be CCI 0035, hands down, 7 days a week and twice on Sunday.
...but match-grade it ain't. Use it for offhand practice, use it for reaction drills, use it for field/animal shooting, use it for pistols (where it is a wonderful round), use it to slug barrels, use it when the grandkids come over...but if you need real accuracy, you're gonna need a better round.
I have a real affinity for no less than SIX .22 LR rounds for different tasks and seasons.
